摘要
介绍了由二级服务器传输跟踪控制数学模型和基于Profibus-DP现场总线技术的西门子S7-400 PLC DCS控制系统共同构成的钢板热处理传输并信号跟踪仿真系统。该系统以精确的交流变频伺服传动和分布式物料实时传输位置的监测校正装置为基础,不仅实现了钢板传输位置的信号模拟仿真跟踪和控制,而且通过与热处理炉加热燃烧控制系统、淬火机及水处理控制系统的数据信息交互,实现完美的热处理工艺处理执行,同时利用摆动传输方式实现连续批量式加热及炉膛容积与热能源的充分利用,进行高效节能生产。经过在线热处理的钢板产品,不仅各项力学性能指标测试数据优良,而且外观板形良好,特别是加工难度最大的淬火板,无需再加工处理。
A steel plate heat treatment transmission and sign track simulation system were introduced which is composed of a secondary automation system and its mathematical model of plate transmission and track control and Siemens S7-400 PLC DCS based upon Profibus-DP technology. Based on the accurate alternating current frequency conversion sevo drive and distributed light barriers device to detect presence of steel plate, the system realized to control the transmission and track of the steel plate＇s position and its simulation sign, to implement the heat treatments on line with information exchange of the burning-PLC, quenching-PLC. The results show that the high-efficiency produce is achieved through swing driving transmission of steel plate by which the continuous and batch production is carried out and furnace capacity and heat energy are fully utilized. Mechanical properties of the steel plate heat treated on line are excellent and its shape appearance is good. Especially, the quenched plate with difficulty in processing can be finished one time.
